Fun-loving grandma filmed downing shots with partygoers in Mexico

Hanging out with your grandma on holiday doesn’t usually end in a hangover. However, when Doreen Grett bumped into three student partygoers in Mexico, she readily agreed to join them for tequila shots in the sunshine.

Grett - who lives in Olathe, Colorado – made sure to upload a picture of the drinking session to her Facebook page, captioning it: “Shots with the girls.”

Her granddaughter, Payton, spotted the photo in her newsfeed, and found it so hilarious that she decided to share a picture of her grandma’s hijinks to Twitter.

“My grandma is in Mexico taking shots with random girls on the beach and posting pics of it with captions like they're BFFs,” she wrote. And so an internet legend was born.

The image immediately went viral, with nearly 20,000 retweets and over 93,000 likes. Many people contacted Payton to praise her grandmother’s style and attitude to life – including one of the women who’d been busy downing shots with Grett in the first place.

The student, named Anna Maria, even posted a video of Grett in action. And, as it turns out, she’s a total pro at downing shots.

Anna Maria then sparked up a conversation with Payton, writing: “We love your grandma so much omfg.

“I’m so glad we met her. She was so sweet and told us all about you and your brother.”

Now we just need to get a date in the diary for a night out with Doreen.
